I have chased this myself and had the following reply from ScrewFix who inquired on my behalf.
Thank you for your patience whilst we have been waiting on an update from Swarfega.
They have advised the following;
We don’t have micro-polymer beads in Swarfega Orange, we haven’t had them in for a number of years now. We moved to a biodegradable cornmeal scrubbing agent at least 5 years ago.
We will of course be updating our description to reflect this change in the product.
